Estimated time preference rates are extremely varied, with many rates being extremely high. Reviewing empirical studies without quantitative synthesis of their findings is largely unhelpful in determining how rates vary according to different factors. This study therefore explores the use of...

Background: The Investigating Choice Experiments for the Preferences of Older People (ICEPOP) programme developed a capability-based measure of general quality of life (QOL): the ICEPOP CAPability (ICECAP-O) instrument. ICECAP-O was originally intended for use in the economic evaluation of...

Health services researchers are increasingly using discrete choice experiments (DCEs) to model a latent variable, be it health, health-related quality of life or utility. Unfortunately it is not widely recognised that failure to model variance heterogeneity correctly leads to bias in the point...

Objective: To identify any differences in response and completion rates across two versions of a questionnaire, in order to determine the trade-off between a potentially higher response rate (from a short questionnaire) and a greater level of information from each respondent (from a long...

This paper reports the first application of the capabilities approach to the development and valuation of an instrument for use in the economic evaluation of health and social care interventions. The ICECAP index of capability for older people focuses on quality of life rather than health or...

This paper reports the results of a best–worst scaling (BWS) study to value the Investigating Choice Experiments Capability Measure for Adults (ICECAP‐A), a new capability measure among adults, in a UK setting. A main effects plan plus its foldover was used to estimate weights for each of...
